Hasan faces the death penalty if convicted in the 2009 rampage that killed 13 and wounded more than two dozen others on the Texas Army post.

Hasan's case had been on hold since August, when he appealed the former judge's order to shave his beard or be forcibly shaved before his court-martial. But last week the U.S. Court of Appeals for the Armed Forces ousted the judge and tossed out his order.

The ruling said the command, not a judge, is responsible for enforcing grooming standards.
